You might be wondering why we should care so much about whether or not people believe that someone can talk to the dead or predict the future. Why should we care if people think critically or make good decisions?

Because it matters. Woo diverts and wastes resources. Woo discourages independent thinking and reason. Woo kills people. And it does not just kill those who follow it blindly.

We do not live in isolation. Living in a society comes with living with the decisions of others. Sometimes, as in the case of government, those making the decisions are doing so for all of us. However, one does not need to be in such a position to ensure that others face consequences for their choices.

Some examples and discussions of the harm caused by failures to think critically about woo are heartbreaking as they include innocent bystanders.
